    • Variational Nonlinear Optimization in Fluid Dynamics: The Case of a Channel Flow with Superhydrophobic Walls 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; ccPICELLA, Francesco; ccROBINET, Jean-Christophe (MDPI AG, 2020-12)
      Variational optimization has been recently applied to nonlinear systems with many degrees of freedom such as shear flows undergoing transition to turbulence. This technique has unveiled powerful energy growth mechanisms ...
    • On the influence of the modelling of superhydrophobic surfaces on laminar–turbulent transition 
      Article dans une revue avec comité de lecture
      ccPICELLA, Francesco; ccROBINET, Jean-Christophe; CHERUBINI, Stefania (Cambridge University Press (CUP), 2020-08)
      Superhydrophobic surfaces dramatically reduce the skin friction of overlying liquid flows, providing a lubricating layer of gas bubbles trapped within their surface nano-sculptures. Under wetting-stable conditions, different ...
    • Sparse Bayesian Learning of Explicit Algebraic Reynolds-Stress models for turbulent separated flows 
      Article dans une revue avec comité de lecture
      CHERROUD, Soufiane; MERLE, Xavier; ccCINNELLA, Paola; ccGLOERFELT, Xavier (Elsevier BV, 2022-12)
      A novel Sparse Bayesian Learning (SBL) framework is introduced for generating parsimonious stochastic algebraic stress closures for the Reynolds-Averaged Navier–Stokes (RANS) equations from high-fidelity data. The models ...
    • Bayesian model-scenario averaged predictions of compressor cascade flows under uncertain turbulence models 
      Article dans une revue avec comité de lecture
      ccDE ZORDO-BANLIAT, Maximilien; MERLE, Xavier; ccDERGHAM, Grégory; ccCINNELLA, Paola (Elsevier BV, 2020-04)
      The Reynolds-Averaged Navier-Stokes (RANS) equations represent the computational workhorse for engineering design, despite their numerous flaws. Improving and quantifying the uncertainties associated with RANS models is ...
    • CFD-driven symbolic identification of algebraic Reynolds-stress models 
      Article dans une revue avec comité de lecture
      ccBEN HASSAN SAIDI, Ismaïl; ccSCHMELZER, Martin; ccCINNELLA, Paola; GRASSO, Francesco (Elsevier Inc., 2022-02)
      Reynolds-stress models (EARSM) from high-fidelity data is developed building on the frozen-training SpaRTA algorithm of [1]. Corrections for the Reynolds stress tensor and the production of transported turbulent quantities ...
    • DNS of turbulent flows of dense gases 
      Article dans une revue avec comité de lecture
      ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccGLOERFELT, Xavier; GRASSO, Francesco (IOP Publishing, 2017-04)
      The influence of dense gas effects on compressible turbulence is investigated by means of numerical simulations of the decay of compressible homogeneous isotropic turbulence (CHIT) and of supersonic turbulent flows through ...
    • Analysis of Dense Gas Effects in Compressible Turbulent Channel Flows 
      Communication avec acte
      ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccGLOERFELT, Xavier (Springer International Publishing, 2019-02-02)
      In this work we investigate the influence of dense gas effects on compressible wall-bounded turbulence. Turbulent flows of dense gases represent a research field of great importance for a wide range of applications in ...
